Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic polyester
Aromatic polyesters like PET have specific subheadings; PBT classified as other if not meeting aromatic criteria.
If ethylene copolymer predominates
Per subheading note (a)(4), classifies by predominant monomer if PBT comonomers fall below 95% threshold.
If chemically modified
Subheading note (a)(3) directs chemically modified polyesters to 'Other' subheading unless more specific.

Import Tips & Compliance
• Provide certificate of analysis confirming PBT monomer content exceeds 95% by weight to avoid reclassification; declare exact polymer composition on entry documents; watch for copolymer blends that may shift to other subheadings
